Computes a log-transformation of x with a small positive bias b,
and an optional logarithmic base.
Usage
logbp(x, b = 1e-06, base = 10^1)
Arguments
- x
A numeric vector or matrix of values to transform.
- b
A small positive offset added to x before applying the logarithm. Defaults to 1e-6.
- base
The base of the logarithm. Defaults to 10.
Value
A numeric vector or matrix with the log-transformed values.
Examples
